Selection Guide
Use the following criteria to determine whether the LJ-V7001 is the right controller for your application:
| Requirement | Recommended Model |
|---|---|
| Standard high-speed inline inspection with PC | LJ-V7001 ✓ |
| Standalone operation without PC | LJ-V7001P |
| Higher accuracy sub-micron profiling | LJ-X8001 (upgrade) |
| Legacy system replacement (LJ-G series) | LJ-V7001 (upgrade from LJ-G5001) |
| Budget-constrained, lower throughput | ZG2-WDS50 (Omron) or LLT2900 (SICK) |

Replacement & Compatibility FAQ
Q: Can the LJ-V7001 replace the older LJ-G5001 controller?
A: Yes, the LJ-V7001 is the successor generation. However, LJ-G series sensor heads are not compatible with the LJ-V7001 — you must also upgrade to LJ-V7000 series sensor heads.
Q: Is the LJ-V7001 compatible with LJ-X series sensor heads?
A: No. LJ-X series sensor heads require the LJ-X8000 series controller. The LJ-V7001 only supports LJ-V7000 series heads.
Q: Can I use the LJ-V7001 with a Siemens S7-1500 PLC via PROFINET?
A: Yes. The LJ-V7001 natively supports PROFINET, making it directly compatible with Siemens S7-1200/1500 PLCs.
Q: What software is required to configure the LJ-V7001?
A: Keyence LJ-Navigator2 (Windows-based, free download from Keyence). The controller also has a built-in 3.5″ LCD for basic setup without a PC.
Q: Do you supply the sensor head separately?
A: Yes. Please specify your required measurement range and we will recommend the appropriate LJ-V7000 series sensor head to pair with the LJ-V7001 controller.
